Answer 1

代码不需要解释。

def getNegativesList(postivesAndNegativeslist):
    if postivesAndNegativeslist is None:
        return None
    elif len(postivesAndNegativeslist) == 0:
        return None
    negativesList = []
    for val in postivesAndNegativeslist:
        if val<0:
            negativesList.append(val)
    return negativesList
print(getNegativesList([2,-3,-5,10,-1]))
